The carving looks like Virginia, a better picture of the carving would help. The trigger guard (my 1st thought) isn't indigenous to the rifle at all. It would help to have the rifle win hand, all of this is pure speculation. If your within a reasonable distance from somebody, take a ride and have somebody look it over, or if your close to CLA territory a lot of the guys will be there next weekend. Dennis and Tim Hodges will be there one of these 2 can help you.
